The S-Curve

Welcome to The S-Curve

Now you will be able to receive the latest announcements, product updates, and our insights on the mortgage market in real time.

The name of the blog, the S-Curve, is a reflection of our logo and the central feature of our prepayment model. S-curves are seen in nature in many phenomenon, from population growth to prepayment and default models. Our first S-curve, in the early 1990s, used the arctangent function, then piece-wise linear functions, and evolved over time to be more complex and vary by FICO, loan size and LTV. This evolution encapsulates both the timeless nature of fundamental relationships and constant innovation to describe them better over time.

We hope you find the information useful and we look forward to your feedback.

    Earth Day

    Since 1970, April 22nd has been the annual day to appreciate our planet and recognize the importance of protecting it.  But more and more, we realize that everyday needs to be Earth Day, and that we need to take better care of the place that gives us life. It’s becoming harder and harder to doubt the legitimacy of climate change, and how we as humans contribute it.  At Andrew Davidson & Co., Inc. (AD&Co) we recognize the dramatic nature of climate change and how it effects our neighbors around the world. As experts in the mortgage market, we’re looking at the ways extreme weather, such as hurricanes, floods, drought, and melting glaciers, affects people’s homes, their way of life—and the availability and price of housing.

    In our December 2020 Pipeline article we anticipated an increasing expectation on the need to measure and disclose exposure to climate change, and laid out some of the analytic challenges. We have focused on studying the existing research, reaching out to climate risk research firms, and understanding the landscape of what is available and what needs to be developed. As we explore different product ideas, we expect to reach out to our existing clients to help us understand better the ways we can continue to deliver leading-edge analytics in this space.

  • Diversity Awareness Lifts all People

    AD&Co Marketing Team

    Thoughts

    To seek "causes" of poverty in this way is to enter an intellectual dead end because poverty has no causes. Only prosperity has causes. – Jane Jacobs, Activist and Author

    Here at Andrew Davidson & Co., Inc. (AD&Co) we have been aware since our founding in 1992 that diversity of all kinds makes for a more interesting culture, a better exchange of ideas, and ultimately better products and services. However, for all of us, globally and in the U.S., there is still a long way to go. We are focused on increasing our sensitivity to diversity and unconscious bias and have made diversity outreach in recruiting, mentorship, vendors, charitable giving—indeed, in every aspect of our business a priority. We have been focused on the fact that every person deserves an equitable life. Our guiding principle is that we are all people and we all deserve to be treated equally. 

    This is especially relevant to issues of housing as AD&Co’s Richard Cooperstein has addressed in the article he co-authored with Ken Fears from the National Association of Realtors (NARS) and Susan Wachter of the Wharton School for Business, University of Pennsylvania, Government-Sponsored Enterprises: Their Viability as Public Utilities published in the journal “Housing Policy Debate,” Volume 31, 2021 - Issue 1: The Mortgage Market in the Time of COVID / Smart Cities, Housing, and Community Development Policy.

    About Freddie Mac Single-Family Credit Risk Transfer

    Freddie Mac’s Single-Family CRT programs transfer credit risk away from U.S. taxpayers to global private capital via securities and (re)insurance policies. The GSE Single-Family CRT market was founded when Freddie Mac issued the first STACR® (Structured Agency Credit Risk) notes in July 2013. In November 2013, ACIS® (Agency Credit Insurance Structure was introduced. Today, CRT serves as the primary source of private capital investment in residential mortgage credit.

    Thoughts

    The January 14, 2021 revisions of the Preferred Stock Purchase Agreements between the Treasury and the GSEs[i] (Government Sponsored Enterprises) along with the Treasury Department Blueprint on Next Steps for GSE[ii] Reform perhaps represent the end of a decade- long effort to create multiple competitive enterprises and end the government support of the GSEs.

    Separating signal from noise is at the heart of what we do at AD&Co. One of the key tools we utilize for that purpose is a sophisticated set of model performance trigger reports. These monthly reports not only alert us to model drift but also point to possible causes for the drift.
